Thank you Redwitch! If dumbbell front raises and dumbbell side lateral raises don't hurt your elbows, you can substitute these exercises.
Side Note: Modified version of the lateral raise would be a bent arm option (arms bent at a 90 degree agngle at the elbow)if the long arm version stresses your elbow joint.
As for the front raise modification, keep a slight bend in your arm as your raise the dumbbell and or turn your dumbbells so that the thick ends face the ceiling and floor.
Hope this helps. Take Care!
